MartinLogan's Motion F200XT in the Planète Haute-Fidélité room wasn't the only speaker in town to employ a Heil Air Motion Transformer tweeter. So did Monitor Audio's 3-Way Platinum 300 3G (for 3rd generation) floorstander ($22,000).

Remember in my first post when I said "How cool it would be if I'd turned into Alternate Rob with a half-million dollar system waiting for him at home?" Well, the system I encountered in one of Filtronique's rooms would fit the bill nicely.
